An optical print head emitting substantially uniform light

摘要

An optical print head, which records an image in accordance with image data on a photosensitive recording medium by exposure/unexposure to light, comprises a light source for emitting light, a light source conversion unit for converting the light into linear light in substantially uniform light quantity in the same direction as a main scanning direction and emitting the linear light. A liquid crystal shutter array selectively passes or shuts out the linear light falling on the recording medium based on the image data.
